To all whom it may canoem:

Be it known that I, W. San- MON, J12, a citizen of the United Statusresidingat Baltimore, the-State Maryland, have invented certain new anduseful Improvements in lllotien f'ic'tum Apparatus, of which thefollowing isa specification.

This invention rel-ates to motion-picture Y apparatus and particularlyto'the reel mech- 10 anism therefor.

One object is to provide a reel adapted to be mounted upon an inclineand loosely support a coil of film in "m'bstantially edgewise positionthereon, with means arranged the interior of said same upon the exterioroperation of the macoil and rewind the ture machme and subsequentlydirecting the film from the machine back to theouter convolution of thefilm coil on the reel, whereby the film is wntinuously unwound andrewound on the one reel.

. Another object ot-the invention is to join ofseparate films, so beprojected that, combined, they may through the machine continuouslywithout "18 the angle plate manipulatlon or intermission.

, A still further. obiect is to provide a comparatively simple andeconomical film reel embodying revoluble rin'g' members capable ofrevolving together or independently of each other and adapted to beengaged by the these revoluhle ring members rather than on the bottom oithe reel.

. With the above and other objects in view,

the present invention consists in the combination and arrangement ofparts hereinafter more fully described, illustratedin the 'accompanymgdrawings, and particularly pointed out in the appended claims, it beingunderstood that changes may be made in the form, proportion, size andminor details :W1tl'1011t departing from' the spirit '9!- sacriincludesa tubular lens lower guide rollers with means arranged from the.innermost chineA in any angle plate 16, one web 1 the machine A and bytightening the his to one of edges of'the film to support, the latter sothat most of the weight of the film is carried by I 21" and upWarlly andrearwardly in a plane substantial y ficiig any of the advantages of theinvention.

In the drawings :-Figure 1 is a view illustrating a motion-picturemachine in side elevation and my improved reel in perspective. Fig. 2 isa front elevation of a movleg-picture machine apparatus illustrating myimproved reel in perspective. Fig. 3 is a sectional view of my improvedreel. Fig. t is a transverse sectional view of. the reel. Fig. 5 is aface view ofthe reel. Fig. 6 is a detail fragmentary section of the reelsupporting arm illustrating the supporting surface for the reel.

Referring now more particularly to the accompanying drawings thereference character Aiudicates a moving-picture machine which may be ofany suitable type and'which holder 10, upper and 1111 and 12-12,respectively, which connected together'in any suitable manner so thatupon operation of the handle 12 mounted on the shaft 13 and by virtue ofsuitable connections between the shaft 13 and the guide roller 12 thefilm 14; may be driven or fed through the machine for the projection ofthe picture in theusual man:

ner.

Mounted on top of the casing of the masuitable manner is an arm 15arranged preferably perpendicularly. Along the upper front edge ofthecasing of the moving-picture machine A is disposed an of which has slotsdown over the front face of the casing of thumb nuts 18 this plate 16may be clamped firmly to the casing of the moving-picture machine.the'webs of this angle plate 16that the perpendicular arm 15 is preterably secured. One means for securing the perpendicular armr15 to'theplate 1615 to provide the arm 15 with afoot piece' 19 through which" maybe passed one or more bolts 20 so as to fasten the arm lo firmly on theplate 16.

The upper end of the perpendicular arm 15is preferably enlarged as at 21with its enlarged portion provided with a flat face which face ispreferably inclined at aforty-five degree angle with are preferablysuitably 17 whereby upon lOOSBIHIIg the thumbnuts 16 may be readilyfitted relation to the axis of the perpendicular arm 15.

The flat face 21' at the upper end of the supporting arm 15 provides asupporting surface for the film reel B. This film reel B may be of anysuitable construction. It

'ride upon the trunnions 25 of the rollers 26 are spaced rings 27 and 28against the inner faces of which the edges of the film C are adapted tobear so that when the film is driven through the machine in a mannerhereinafter explained the edges of the same may engage either one or theother of the rings 27 and 28 and cause them to rotate. The film isarranged loosely over the rollers 26 and they are supported mainly ontheir edges by the revoluble rings 27 and 28 incident to the inclineddisposition of the reel and the winding and unwinding of the To supportthe film reel B on the inclined face 21' of the head 21 of theperpendicular supporting arm 15 the annular flange 27 maybe providedwith a headed projection 29 adapted to be easily removably seated in thenotch 30 at the upper edge of the head 21 with the head 21 havingprojecting from its flat face 21' the pins or studs 31 designed toengage against the outer face of the bottom portion of the annularchanneled member which forms the body of the reel. 'In this way the reelis hung or suspended from the upper end of the perpendicular arm 15 andthereby firmly supported in operative position.

As the-film coil on the reel B is rotated the inner convolution isdirected from the reel out through the film passage 24 in the reel toand over the guiding element 32 which is preferably in the form of aroller, as shown, and which projects from the flat face 21' of the head21 at substantially a right angle to the longitudinal axis of the arm15, extending into the area bounded by the bottom of the annular bodymember of the reel and preferably midway of opposite sides of said bodymember on an imaginary horizontal line adjacent the bottom edge of thefilm passage opening 24. From this guide roller 32 the film, is drivenby the driving mechanism between the aforesaid shaft 13 and the guideroller 12 and the driving connections being element 32 with the guidingelements 32 and 33 arranged at an angle with relation to the plane ofthe guide rollers 11-11' and 12-12 so that the run of the film whichextends beyond the guiding element 33 may be deflected to one side ofthe tubular lens holder 10 so as not to interfere with the pictureprojecting from that part of the film passing between the guidingrollers 1111 and 12-12. The film is continued upwardly from the guidingelement 33 off to one side of the tubular lens holder 10 as just statedto a guiding element 34 which latter is preferably disposed in aparallel plane with the guiding element 32- and which guiding element 34is preferably carried by an arm 35 secured to the perpendicular arm 15in the rear of the head 21, as shown. This guiding element 34 may besecured in any suitable manner on the interior of the usual filmmagazine casing (not shown) instead of being secured to the arm 35, asspecified. In any event, the

function of the guiding elements 33 and 34 is to direct the film back tothe reel so that it may be returned to the outermost convolutions of thefilm coil on the reel B.

It will thus be seen that I 'provide a film reel and means for guidingthe film whereby the film coil on the reel may be loosely carriedthereby and directed from said reel from the innermost convolution ofthe film out of the plane of the reel to the motionpicture machine andthen guided from the machine back to the outer convolution of the filmcoil on the reel whereby the film is continuously unwound and rewound onthe one reel. The result is that I obviate the practice of unwinding thefilm from one reel to another and subsequently shifting the positions ofthe reels to repeat the pictures. By virtue of my improved reel I amenabled to provide for a- .continuous performance by continuouslywinding and unwinding the film on the one reel, thereby obviating thenecessity of shifting one reel with relation to another and alsorendering it possible to simply remove the reel with its film thereon atthe end of a performance and substitute another reel with a film thereonand continue to wind and unwind the film on the one reel until the endof the performance.

What is claimed is 1. In a motion picture apparatus, a reel, means forsupporting said reel, means for winding and unwinding a film thereon,rollers journaled in said reel and rings rotatable upon the trunnions ofsaid rollers. j

2. In a motion picture apparatus, a reel, means for mounting said reel,means for winding and unwinding a film thereon, said reel comprising twosections, means for removably connecting said sections, parallel flangesformed upon said reel, in spaced relation to each other, said flangeshaving openings provided therein, rollers journaled in said openings andrings rotatable upon the trunnions of said rollers and slidably engagingthe outer ends of the rollers. and inner sides of the flanges,substantially as set forth.

In testimony whereof I aflix my signature in presence of two witnesses.
